Patent CA-2471561-A1 (CA)
Inventor: ELGNER ROGER
IPC: B29C49/32
Filed: 2003-02-11
Abstract: A mold for use in blow molding has a first fixture (12) and a second fixture (14). The fixtures (12,14) correspond to typical mold halves or portions. The first fixture (12) includes drive means (40), typically in the form of pins (46), while the second mold fixture has drive receiving means (66), typically in the form of holes (70), to receive the pins (46). When the second mold fixture (14) is in registration with the first mold fixture (12), the pins(46) or other drive means (40) are extended to lock and locate the two fixtures (12,14) together. Blow molding can then be carried out without the need of the typical blow molding presses. A method of blow molding involves the use of a robotic arm (84) to move the relatively lightweight second mold fixture (14) described above beneath an extrusion head (102) to accept a parison as it is being extruded so the parison is contained within the mold cavity (60). After extrusion is complete the arm (84) moves the second fixture (14) toward the first fixture so that the fixtures (14) can be located and locked together. A single robot (110) using a single extrusion head (102) can serve several mold stations depending upon cycle times.

Title: A system and process for generating high dynamic range images from multiple exposures of a moving scene
Inventor: KANG SING BING
IPC: G06T5/50
Filed: 2004-06-18
Abstract: A system and process for generating a high dynamic range (HDR) image from a bracketed image sequence, even in the presence of scene or camera motion, is presented. This is accomplished by first selecting one of the images as a reference image. Then, each non-reference image is registered with another one of the images, including the reference image, which exhibits an exposure that is both closer to that of the reference image than the image under consideration and closest among the other images to the exposure of the image under consideration, to generate a flow field. The flow fields generated for the non-reference images not already registered with the reference image are concatenated to register each of them with the reference image. Each non-reference image is then warped using its associated flow field. The reference image and the warped images are combined to create a radiance map representing the HDR image.

Title: Vascularized human skin equivalent
Inventor: BOTHWELL ALFRED L M
IPC: A61K35/12
Filed: 2003-04-14
Abstract: Clinical performance of currently available human skin equivalents is limite d by failure to develop perfusion. To address this problem we have developed a method of endothelial cell transplantation that promotes vascularization of human skin equivalents in vivo. Living skin equivalents were constructed by sequentially seeding the apical and basal surfaces of acellular dermis with cultured human keratinocytes and Bcl-2 transduced HUVEC or umbilical cord cells sequentially. After orthotopic implantation of grafts comprising cultured human keratinocytes and Bcl-2 transduced HUVEC cells onto mice, the grafts displayed both a differentiated human epidermis and perfusion through the HUVEC~lined microvessels. These vessels, which showed evidence of progressive maturation, accelerated the rate of graft vascularization. Successful transplantation of such vascularized human skin equivalents shoul d enhance clinical utility, especially in recipients with impaired angiogenesi s.

Title: Vending machine tracking system with controlled switching device
Inventor: DARLING JIM
IPC: G07F9/00
Filed: 2005-01-24
Abstract: A tracking system counts events in the operation of multiple machines or devices over a wide geographic area. One or more reed switches for transmitting an electrical signal to a tracking device is mounted to the stationary frame of the coin mechanism and actuated by a magnetic element mounted to the revolving coin carrier. In one embodiment a controller is programmed to pass a pulse from the reed switch to a counter only once during every preset interval, for example five seconds. This helps to defeats attempts to artificially increase the vend count by jiggling the handle at the point where the magnet passes the reed switch, to cause multiple passes within a single rotational cycle of the coin mechanism. Additional prevention is provided in a further embodiment having two reed switches that must be actuated in sequence before the controller will pass a pulse to the counter.

Filed: 2005-04-12
Abstract: The drywall measuring tape is a tape measure extendably contained within a housing, including a laser light source, such as a laser diode, located on each side of the housing. Each laser light source projects a focused light beam perpendicular to the extended tape measure, and in a plane parallel to the housing base. Thus, when the tape measure is extended across a wall with the housing base flush against the wall, one of the laser light sources projects a reference spot onto the ceiling, while the other projects onto the floor. This allows a measurement to be taken horizontally across a wall in reference to a point on the ceiling or floor. Additionally, the drywall measuring tape may include a T-square bracket on the housing base, disposed so that the drywall measuring tape can be quickly aligned with a surface edge for measurement perpendicular to the surface edge.
